Abstract
A reminding device of door opening erects read-write unit, radio mark and safety alarm unit on the door so safety alarm is generated when the door is opened up to certain distance so as to have read-write unit lost signal of the radio mark.
Description
(1) technical field:
The present invention relates to the door opening indicator device, belong to wireless identification tag and read write line technical field.
(2) background technology;
Infrared ray or mechanical testing fixture such as room door, automobile door, refrigerator doors are used in the switching of all at present more, door for microwave oven, but be subjected to surrounding environment influence easily, service time, long sensitivity meeting reduced, there is potential safety hazard in the open and close state of prompting door that can't be correct.Read write line (card) has been installed in door recently, on the car door of automobile, cooperates wireless electronic tag, and the key that contactless IC-card chip is made is as the door lock of door.The present invention increases wireless identification tag or contactless IC-card chip on door, cooperate read-write (card) device, opens read write line when door and loses the wireless identification tag signal, and read write line sends signal and starts safety alarm device.
(3) summary of the invention:
For solving the switching testing fixture of existing door, be subjected to surrounding environment influence easily, service time, long sensitivity meeting reduced the problem of the open and close state of prompting door that can't be correct.Door opening indicator device of the present invention adds read write line on door, wireless identification tag, safety alarm device.When door is opened certain distance, read write line loses the wireless identification tag signal and just produces security alarm sound.The present invention has simple in structure, and service time is long, safe advantage.
The present invention finishes by following technical measures:
The present invention adds read write line at door, safety alarm device, wireless identification tag.
(4) description of drawings:
Below in conjunction with accompanying drawing structure of the present invention is described further:
Fig. 1 is the enforceable structural drawing of door opening indicator device of the present invention.
Wherein: 1 doorframe, 2,3 read write lines, 4 safety alarm devices, 5 wireless identification tags.
(5) embodiment:
Embodiment: structure of the present invention as shown in Figure 1, doorframe 1, the door 2, read write line 3, safety alarm device 4, wireless identification tag 5.
Example 1: can increase read write line 3 in doorframe 1 the inside, door 2 the insides increase wireless identification tag 4.
Example 2: can increase wireless identification tag 4 in doorframe 1 the inside, door 2 the insides increase read write line 3.Read write line 3 can be placed on any position with respect to wireless identification tag 5, a inside.Read write line 3 connects safety alarm device 4.When read write line 3 loses the signal of wireless identification tag 5, start safety alarm device 4, safety alarm device 4 is sounded, and light or other signals are installed in any position of door.Wireless identification tag 5 also can use contactless IC-card chip.
In sum, more than be part embodiment of the present invention, but be not in order to restriction the present invention.All according to creative spirit of the present invention and feature, pattern, increase read write line at door, safety alarm device, what cooperate that the wireless identification tag signal can the inspection door open mode changes a little all should be in protection scope of the present invention the inside.
